TRANSFER-BINDER.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed December 30, 1912. Serial No. 739,186.

To all whom it may concern Be it known that I, SAMUEL M. Dows'r, a

' citizen of the United States, residing at Ohicago, in the county ofCook and State of Illinois, have invented new and useful Improvements inTransfer-Binders, of which the following is a full, clear, and exactdescription.

My invention relates to temporary binders and particularly those adaptedto bind together one or more copies of a newspaper, periodical,magazine, or similar publication, in a compact and convenient manner sothat the same may be readily handled by the reader.

The principal objects of my invention are to provide a binder theexpansibility of which for binding purposes is practically limitless andwhich owing to its novel construction and arrangement of parts will notmutilate the publications bound therein; also to provide a back for thecovers of such a binder that can expand correspondingly; to make itpossible to withdraw any one or more of the bound publications withoutdisturbing the other; and to accomplish these and other objects bysimple and economical means, substantially as hereinafter fullydescribed and as more particularly pointed out in the claims, referencebeing had to the accompanying drawings forming a part hereof, in which,

Figure 1 is a view of one of my improved binders showing the parts inperspective and separated one from another. Fig. 2 is a top plan view ofmy improved binder. Fig. 3 is an edge view thereof. Fig. 4 is anenlarged sectional view taken through one of the extension posts showingthe samefin detail and provided With an extension member.

Referring to the drawings, A, A, represents the rectangular-shapedcovers of my binder that are hinged along their rear or back edges byflexible portions B to clamping-plates C and C. The above named parts ofmy invention may be of any well-known or approved construction, and saidclamping-plates C and C", usually consist of a comparatively narrowstrip or bar of metal 0 that is covered or surrounded with leather orother suitable material. Clamping-plate C is provided at or near eachend with a vertically disposed sectional post that projects at rightangles therefrom and is tapped securely into a screw-threaded hole cutin said plate and is adapted to extend through opening 3 bored throughthe upper clamping-plate G in alinement with the same. These sectionalposts are a well-known feature of loose-leaf binders, and consist of oneor more cylindrical sections 4 that have screw-threaded tenons mextending centrally from one end, and a screw-threaded hole y in theother end. One of the sections of each of these posts is tapped into andrigidly secured to each end of clamping-plate C,.and the other sections.areadded thereto by simply screwing the tenon on the end of the one intothe hole in the adjacent end of the other, until the posts are ofsuitable length to bind the publications between thecovers, and permittheir unsecured ends to extend up through the openings 3, 3, of theupper clamping-plate O. The unsecured ends of these sectional posts,preferably, extend a slight distance above the upper surface of theclamping-plate G, where they are provided with suitable screw-heads-5the shanks 4. of which are tapped into the screwthreaded holes in theupper ends of said posts.

Said heads are each provided with a skirted portion 5 that extendsconcentrically around the shank 4 and provides a channel or recess intowhich the upper end of the post extends and is seated when said head isscrewed down securely thereon. The edges of skirts 5 are adapted toengage the margins of the openings in the clamping-plate 5 through whichthe sectional posts pass, when heads 5 are screwed into said sectionalposts, and

permit a compression of the back of the binder corresponding to thelength of said skirt so as to render the said binder more compact.

The magazines or periodicals are preferably held in place between theclampingplates by means of a flexible metallic tiestrip 6 which is of alength corresponding to the distance between the centers of the postsand is of comparatively narrow width throughout except that its ends 7are enlarged and bifurcated, substantially as shown. One of these ties 6is inserted between the leaves near the back of each magazine and theyare then placed on the stiifened longitudinal edge of a back cover sothat the bifurcations of the ends of the ties will embrace the sides ofthe posts 2. The clamping-plate of the top cover is then clamped downinto osition, and thereupon the publications in the binder will befirmly held be tween the covers.

In order to confine and protect the back edges of the publications in myimproved binder, I have provided a novel back for the binder whichconsists of a strip of flexible binding fabric 8, that-is, preferably,slightly less in length from its top to its bottom than the distancebetween the binding post 2, andone longitudinal edge 9 of thisbackmember is, preferably, stiifenedby inserting andsecuring a flatmetallic stiffening-plate 10in. thehemmed edge thereof. The ends 11 ofthis stiffening-plate 10 extend beyond .the top and. bottom edges of theback-member andare adapted to engage the posts 2, in the vsame manner asthe retaining tie-strip 6, above mentioned One of the surfaces of theback-member 8 is, preferably, provided with a plurality of scores 12that extend parallel'to the reinforced edge and when said back is placedabove the uppercover of the magazine it is folded or 1 creased along oneof said scores, so as to conform to the thickness of the publications tobe bound, while the remaining portion is inserted under or below thelowermost sheet of the material being bound. After this is done theclamping p late C of the top cover is placed in position on the postsand the whole binder'clam'ped together by means of the screw-heads.

It has often been found desirable to insert an index or fly-leafinibinders of this type for one purpose or another, and this I prefer todo by securing a stiffeningcplate 14 to one edge of a ruled sheet ofpaper 15,

the ends of said plate having bifurcations 16 in its ends that areadapted to beengaged with the posts 2 before the binder is clampedtogether. .7 I lVhile I have shown and described my invention inconnection with a two-post binder, and with certain arrangements andcombinations of elements, it, of course, is obvious that numerousequivalent parts may be employed without materially departing from thespirit of my invention, and all such changes and modifications, I.desire it understood are to be included within the scope of my inventionas embodied in the appended claims.

What I claim as new is: e.

2. A temporary binder comprising removable front and back covers therear edges of which are adapted to clamp printed matter between them,binding posts therefor, a removable expansible flexible backmember oneedge of which is adapted to be clamped between the front clamping-plateand the adjacent printed matter, and the opposite .end of which isadapted to be clamped. between the back clamping-plate and the adjacentprinted matter, and a removable tie-bar inserted in contact with thesheets of printed matter and extending be yond the upper and lower edgesof said back-member and provided with substantially concave recesses inits ends that e11- gage said posts.
